The Automatic Kjeldahl Analyzer! It’s an impressive instrument that combines distillation and titration functions for precise nitrogen analysis. Let’s break down some of its key features and specifications:

1.  Automatic Cleaning: The inclusion of automatic cleaning features ensures operator safety and efficiency. It covers cleaning of receiving cups, alkali and boric acid pipelines, and acid washing.

2.  External Titration Cup: This feature allows real-time monitoring and control of the entire testing process by the operator. Having visibility into the titration process enhances accuracy and reliability.

3.  High-Precision Charging Pump: The use of 4 KNF pumps ensures accurate dosing and precise liquid volume measurement. This is crucial for obtaining reliable results.

4.  Real-Time Temperature Detection: If the distilled liquid temperature deviates, the system halts operation. This safeguard ensures experiment accuracy and prevents erroneous results.

5.  Integrated Printer: Immediate hard copies of results can be obtained for documentation purposes. Having a built-in printer streamlines the reporting process.

6.  Functions: The analyzer includes various functions such as a variable steam generator, monitoring of cooling water pressure and temperature, automatic alkali solution addition, dilution with water, receiver solution addition, and more.
